Hi and Welcome! I think those Caladiums that you have in pots there might need a "rest" aka a dormant period, for a month or two, so I'd put the pots somewhere shady, maybe under an overhang so they don't get too soggy if it rains, and leave them be until, say, April. Then pull them out, add some fert and maybe an inch or two of fresh potting soil and start watering them again. They will come back, I'm sure.
I agree with your other advisors above, you can plant your new bulbs just about any time. If the weather stays cool, you may not see them jump up right away, they will know when to start up. Once you see them up, fertilize and water so they will make lots of leaves, which will make big, new bulbs for you for next year.
I've planted them in fall, and had them live through January, then die back and stay dormant all through the hot, wet summer and come up again in the fall. In fact, I think I had the same ones as you - Florida Beauty.
